Specification of Letters Patent;

Application filed July 28, 1913. Serial No. 781,616.

To all whom it may concern:

Be it known that I, CHARLES H. Born, a citizen of the United States, residing at Brawley, in the county of Imperial, State of California, have invented certain new and useful Improvements in Excavating-Madeclare the follow-. ing to be a full, clear, and exact description of the invention, such as will enable others skilled in the art to which .it appertains to make and use the same.

This invention relates tothat type of excavating machines described in U. S. Patent No. 910,864t, issued to me on an. 26, 190?).

' An object of the present invention is to improve the excavating conveyerby mount- .ing the-same for-transverse sliding movement on the main frame and for adjustment vertically-whereby the excavating conveyer may be manipulated to suit various cond tions of service indredging ditches and the like.

A further object is to generally improve buckets by the provision of lunged doors which are auto-- matically operated to dump. the buckets when the latter are elevated to a'point suitablefor discharge.

With the above objectsin viewthe invention consists of certain novel details of construction'and combination of parts hereinafter fully described and claimed, it being understood that various modifications may be made in the minor'details of construction within the scope of the appended claims.

In the accompanying drawings illustrat- Figure 1 is a plan view of the excavating Fig. 2 is a side elevation of the machine. Fig. 3 is a rear elevation of the machine. Fig. 4 is an enlarged longitudinal sectional view through the excavating conveyer taken on-the line H Fig. 1. i

Fig. 5' is an enlarged cross sectional view the line 5-5 Fig. 1 showing the conveyer driving shaft and its mountings.

Fig. 6 is a rear elevation showing the con-- veyer moved outwardly from the position shown in Fig.

Referring now to the drawings in which like characters of reference designate similar parts, 10 designates in general the frame of the machine, the-same including longitudinal sills 11 connected at intervals. by cross sills 12, the frame being supported at the rear end by spaced ground wheels 13 and at the front end by a dirigi'ble ground wheel 14:. The two rearmost cross sills 15 form a track.

Mounted to slide. across the machine on this track is a carriage comprising a pair of standards 16 which are connected respectively to angleiron bars 17 that extend along the track, there being rollers 18 and 19 carried by the standards and bars and riding upon the track, the bars being retained on the track by means of yokes 20 carried by the bars at intervals apart and embracing the inner sides of the cross sills 15 forming the track. The standards are braced by guy wires 21 extending diagonally between the standards, while the bars 17 are braced by diagonal braces 22, and both the standards and bars are mutually braced by inclined braces 23. The carriage thus constructed may be moved back and forth along the track as desired.

The excavating conveyer about to be described is suspended from a single sleeve bearing 24 which projects transversely through vertical slots 25 formed in the standards, there being guide boxes 26 disposed on the sleeve bearing and slidably'fitting in said slots. A feed screw 27 is threaded imthe top of one of the standards and is turnably secured to one of the boxes 26, the feed screw being equipped with a handle lever 28 which permits of the feed screw being rotated to raise or lower the sleeve bearing bodily in the standards and thus adjust the secured end of the excavating conveyer vertically as desired.

The excavating conveyer comprises a pair of parallel sills 29 which are provided upon adjacent ends with bearings 30 which loosely receive the projecting end of the sleeve hearing and pivotally attach the sills to the sleeve bearing. The free ends of the sills are connected by a hanger yoke 31 and are further connected by a bail 32 which is secured to the cable 33 of a swinging boom 34 carried by one of the cross sills 12 of the main frame, the cable being controlled by means of a Windlass carried by said cross sill at the foot of the boom. As will be understood, by actuating the Windlass the free end of the Patented Dec. 17, 1918. i I

excavating conveyer may be swung up or able bearings and a similar pair of large flange wheels 3?? are secured to a shaft 38 p 45 at the passes up between the'sprockets 42 and then the flange wheel sprockets 39 and a pair ofdriving sprockets 42 which are secured to stub shafts 43 carried by the sills 29. These driving sprockets are of relatively small diameter and engage the underneath sidesof the sprocket chains, such sprockets furthermore projecting up between-the sills 29 so that the lower sides of the chains are carried abruptly upwardly between the sills when passing over these sprockets.

Secured, at spaced intervals to and spanning the sprocket chains 41 are buckets 44 each being in the form of a scoop with ears and the sprocket chains pivot pins 46 are passed, the rear end of each bucket being loosely hung from the sprocket chains through the instrumentality of links 47 which are pivotally attached to the rear edges of the bucket top and to the sprocket chains. A door 48 is hinged at the front end to the ears by means of pivot pins 49 and is normally swung up into the bucketagainst the top thereof by the entering mud when thebucket enters 'the earth; The doora is provided -with substantially triangular cars 50 which extend 11 through the ske'le-o ton top 51 of the-"buc et. As the bucket turns down at this point for dumping the earth upon the bank of the ditch being ex: cavated, the ears 5O impingeagainst but ment plates 52, ofv triangular form and which are bolted to the sills 29 and extend ther'ebelow, with a resultant rocking for-f 1' of "excavating buckets mounted on, said 100 wardly of the door during passage of the bucket along' and underneath these abut- .ment plates with a resultant ejection o-f-the earth from the bucket. The buckets-are .thus dumped in succession whereby the ex 1? a frame, a",track on said frame extending 105 cavated earth is piled on the bank of the ditch,

position ,of the carriage upon the track. The shaft 53projects through the sleeve bearing and is there equipped with a gear 59 which meshes with a gear 60 on the adont upper corners through which .1 bu k v i;

jacent stub shaft 43. The sleeve bearing 24 spacing bolts 62 and spacing tubes 63' coupling the flanged ends together. A gear 64 is fixed on the shaft 53 between the flanges 61 and meshes with a gear 65 on the adjacent stub shaft 43.

Themachine above described may be advanced'along the ditch by means of a cable 66 one end of which may be-fixed to any stationary support and the oppositeend secured to a Windlass 67 driven by the gas engine 5.4 through a suitable power transmission mechanism 68, as described in my former patent, or the machine may be drawn along by a traction engine, as preferred,

that by virtue of the sliding carriage, .the

From the above description it will be seen excavating conveyer may. be moved transversely across the rear end of the machine to operate in wide ditches, and to accommodate this function, the rear axle 69 is formed of a plurality-of telescoping members 'so that it may be extended outwardly to space apart the rear ground wheels 13 of the ma chine and positively prevent tilting of the machine when the excavating conveyer is moved outwardly as shown in Fig. 6. i

It will also be seen that by virtue of the feed screw, the secured end of the excavat- ;ing conveyer may be raised or lowered as desired to suit various conditions of service.
